Several years ago, when I had more time on my hands than common sense, I went through the Buck catalogs and listed every production model in each catalog. There were a few catalogs missing, and I probably made some errors. However, once you have a database you might as well use it. The catalog data end with 2014, and someday I may bring it up to date. With a little manipulation I came up with a list showing the number of new models for each year. You'll notice that starting around the year 2000 the number of new models increases. I think the main reason for that is that BUCK made a slight change. For example if a knife was available in three grades of steel then that meant that there were three different models—think Avid, Select, Pro. Anyway, here is the list.
